### ⭐⭐ 







  
  
    Terrible box and warped washers
  

*by M***Y on Reviewed in the United Kingdom on 5 June 2020*

The box the washers comes in is terrible, the smallers washers can get under the dividers and end up mixed up. Took me 30 minutes of sorting to fix and if I was to move it they start to mix again. Have fixed dividers instead of the plastic, movable inserts.Secondly, around 10% of the washers are badly warped and are not usable.All in all a poor product
